Intestinal obstruction in acute inhalational toluene 2,4-diisocyanate gas toxicity.

The international journal of occupational and environmental medicine, 2013
The isocyanates are widely used as precursors of polyurethane products, as well as carbamate insecticides. Toluene 2,4-diisocyanate (TDI) is one of the most important commercially used isocyanates. Humans may be exposed to TDI by inhalation, ingestion, dermal and eye contact.
